The enterprise cloud company is touting a more "immersive" experience this time around with a new user interface that promises faster scrolling and rendering.

With boosted preview support for more than 100 file types, the upgrade includes full text search within documents, new grid views (and the ability to move, copy and delete multiple files at once), and recommendations for partner apps particular to each file.

David Still, vice president of mobile products at Box, reflected in a blog post on Wednesday that the company is continuing to "find ways to improve how people engage with their content and collaborate with each other on Post-PC devices."

While he didn't provide a timeline or a roadmap, Still promised that Box is following up with similar investments on its Android, Windows Phone, Windows 8, and mobile browser apps.

New features aside, Box has also planted a substantial incentive to get new users onboard and online: 50GB of free storage space.

Box has run promotions like this in conjunction with mobile launches before, including the iPad and even dating back to the HP TouchPad in summer 2011.

Nevertheless, compared the regular freebie allotment of 10GB, which is even generous compared to some other cloud storage providers, 50GB of free space is still considerable in this digital day and age.
